ABSTRACT
Lactic acid bacteria, found in heterogenous niches, are known for their health-endorsing properties and are in demand as prospective probiotics. Hence, the scientific community around the globe is in continuous search for novel and new potential strains with extensive applicability and minimum risk. In this context, the present study evaluated the efficiency of Lactiplantibacillus plantarum (P2F2) of human origin, a highly autoaggregating and coaggregating (with pathogens) strain, for its colonization, growth promotion, and immunomodulation. Results indicated moderate hydrophobicity on adhesion to xylene and n-hexadecane and weak electron-donating properties with chloroform. The biofilm of P2F2 formed on polystyrene was strong and highly correlated to exopolysaccharide production. The autoaggregation was moderately correlated with hydrophobicity and biofilm production. It was noted that the P2F2 strain modulated the gut microbiota and increased intestinal villi length in Wistar rats. The lipid and glucose profiles remained intact. P2F2 treatment increased the activity of reactive oxygen species-generating cells in the peritoneal cavity, besides augmenting the mitogen-induced splenocyte proliferation and maintained the immunoglobulins at the normal level. Results from this study conclusively suggest that the strain P2F2 adheres to the intestine and modulates the gut ecosystem besides enhancing cell-mediated immunity without altering the serological parameters tested.
